VIRGIL H. WINOHELL, OF OLIVE, NEW YORK.

CHURN-POWER.

SPECIFICATION forming part of Letters Patent No. 225,777, dated March 23, 1880,

Application filed January 6, 1879.

To all whom it may concern:

Be it known that I, VIRGIL H. WINCHELL, a citizen of the United States, residing at Olive, in the county of Ulster and State of New York, have invented a new and Improved Power Apparatus for Churns, Pumps, 850., which is fully described in the following specification.

My invention consists of a hand-lever-power contrivance for working churns, pumps, and other reciprocating devices, which is so contrived that a hand-lever to be worked by the operator is made to impart two motions to a secondary lever to one of its own, which secondary lever is made to work the churndasher, pump-rod, or other article; or, if preferred, it may be made to operate a third lever in like manner as it is operated by the first, and thus again multiply the motion of the primary lever. The levers are mounted in standards, which are attached to a base that is contrived for readily attaching temporarily to the top of a churn; and with the main lever, which is by preference made to work in a vertical plane, there is combined a spring, in which someof the power of the down motion is stored, to be given out again on the rising motion, and thereby counteract the gravity of the hands and arms of the operator on the upstroke.

The accompanying drawing is a side elevation of my improved power apparatus as applied to a chnrn, which has a part broken out to shown the interior.

A represents the churn, across the top of which is a small beam of wood, B, temporarily attached by bolts D and screws G, or other suitable means, to facilitate the ready application and removal of the same, and which in practice will also be adjustable along the beam for the attachment of it to churns of different dimensions across the top, and also otherwise modified to suit the dewice to which the power apparatus is to be applied.

E is a standard near one end of said beam, in which the handlever F is pivoted, and G is a standard near the other end of said beam,

' a little higher than standard E, and having about the same horizontal plane as the pivot of lever F is in, and the long arm extends horizontally over the center of the churn, to be connected to the dash-rod K.

N ow, the main lever F is coupled tothe free end of short arm H by the toggle bar or link L, and the range of the movements of the joint M of the lever with said bar is about equal, both above and below the plane of the pivots N and O, as indicated by the dotted lines in the drawing, and thus a single movement of the main lever makes a double movement of the other, thereby making more speedy movements of the dasher than it is convenient for the operator to makethat is to say, it is less laborious for the operator to expend the power to make two movements of the dasher in one long movement than in two shorter and quicker ones.

The spring P is combined with the handlever F in such arrangement that when the hands of the operator move downward and add their weight to the power exerted by him it is stretched and put in tension, so as to assist to some extent, on the upstroke of the hands, to counteract their gravity.

As before stated, if quicker motion is required for the dasher, pump-rod, or other device to be worked by the apparatus, the long arm 1 may be made to work another lever in the same manner as it is worked by the main lever.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is i 1. The combination, in a hand-power apparatus, of two lovers, F and H I, and the connectin g link or bar L, when the short arm of lever F is connected to the short arm of lever H I by the link L, and all arranged substantially as described.

2. The combination of main lever F, link or bar L, elbow-lever H I, dash-rod K, and spring P, substantially as described.

3. The combination of base B, connecting devices 0 D, standards E G, main lever F, link or bar L, elbow-lever H I, and spring 1?, substantially as described.
